Figure 3. Aptamer characterization.

Figure 3

A. Binding specificity of the aptamer obtained from clone 24 & 51 by surface plasmon resonance (SPR) technique using Biacore 3000. Various concentrations of α-bungarotoxin (1, 10, 20, 30, and 40 µM) were passed through the aptamer which was immobilized on a streptavidin coated sensor chip. The obtained sensorgrams demonstrate the aptamer binding to α-bungarotoxin; B. Predicted structure of the obtained aptamer using the DNA folding platform from mfold web server [26].
